UNITED STATES PATENT oEEicE.

S. H. MERRIDITH, OF OXFORD, OHIO.

CHURN.

Specification of Letters Patent No. 41,525, dated February 9, 1864.

To all who/m. t may concern Be it known that I, S. I-I. MERRIDITH, of Oxford, Butler county, and State of Ohio, have invented certain new and useful Improvements in Churns; and I hereby declare that the following is a true and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Figure l in the annexed drawings represents a vertical section of my churn. Fig. 2 represents an end elevation of the same. Fig. 3 represents a plan view of the circular dasher inverted. Fig. 4L is a representation and plan view of the bed piece.

Letter (A) in Fig. l, represents the body of the churn.

(D) represents a horizontal shaft passing lengthwise through the body The shaft (D) has a small gudgeon at one end which works in a cleat nailed inside of (A) and a larger gudgeon at the other end which extends through (A) and furnishes an axle for the wheel There are four rows of arms marked (b) which are placed spirally around shaft The arms (Zn) are inserted at right angles with shaft -(D) and the blades so formed as to present on their broadest surface an angle of about forty-live degrees in reference to the shaft.

(B) represents the driving wheel which is hung on the stud (I)-the stud (I) resting at its opposite end in the slide (O) which plays vertically in the frame See Fig. 2.

To the lower part of slide (O) the lever (F) is fastened by a screw bolt J. The lever (F) being made to play on the bolt can be raised or lowered to throw the wheel (B) into gear with either wheel (C) or wheel (E). Then (B) is in gear with wheel (E) motion is given to shaft (K) by means of the bevel wheel (L). Then the butter is to be collected (B) is thrown out of gear with and in gear with (C) by means of the lever (F). The shaft (K) is tubularthe tube beingdesigned to convey the milk through two holes in the bottom of the shaft (K), and introducing it between the circular dasher (M) and the bed piece (N) where it is subjected to the action of the radial elevation on the lower surface of the circular dasher (M), and on the upper surface of bed piece (N), which is immovably fastened to the platform (T).

The circular dasher (M), and bed piece (N) are constructed as follows Dasher M descends at a small angle from the base of shaft (K) and has a iiange s, around its circumference which extends below the upper surface of bed piece (N) having sufficient space between this flange and the periphery of (N) for the milk to escape. The lower face of (N) represented by letter (V) has four thin radial elevations (I) extending from near its center to its circumference.

-These elevations may vary in height to suit the size of the dasher Elevations (I) are equidistant from each other and are intersected by the circulaielevation Between the circle and the flange (s) there are four other similar elevations marked (d) which are placed midway between the elevations (l). The upper surface of bed piece (N) is furnished with elevations similar tothose on (M) except that there are springs in them to admit of elevation passingthrough them. See Fig. l and Fig. 8. The bed piece (N) ha's a iiange on it of the same height as the radial elevations on its face.

My machine is operated by means of a handle on wheel (B),-(B) being irst in gear with which communicates motion to shaft (K) through which the milk is conducted to the space between dasher (M) and bed piece (N)-is then subjected to the radial elevations on (M) and as already describedhand then escapes through the opening left for its cups into the body of the churn-where the butter is collected in the manner indicated above.

Having thus described my machine what I claim and desire to secure by Letters Pat- S. H. MERRIDITH.
